Water culture device for cut branch of forest

Abstract

The invention discloses a water culture device for a cut branch of a forest, which is characterized by comprising a water culture chamber (1) in which a vertical plate (2) for horizontally or obliquely accommodating the cut branch of the forest (5), a water injector (3) arranged on the top of the water culture chamber (1), and a water supply device connected with the water injector (3) through a water injection pipe (17) so as to supply water to the water injector (3). In the water culture device, the cut branch of the forest is horizontally or obliquely arranged, an environment that a branch is grown on a trunk of a tree at a certain angle is fully simulated, water culture solution vertically fall back from top to bottom and flows through a cut end of the cut branch of the forest, the oxygen in the water culture solution is sufficient, the cut branch is uniformly supplied with water, the water culture effect is good, and the water culture device is light in structure and convenient to move.

Description

technical field [0001] The invention relates to a liquid culture device, in particular to a liquid culture device for plant cutting and cultivation. Background technique [0002] Hydroponics is a new type of soilless plant cultivation, also known as nutrient liquid cultivation and hydroponic cultivation. Its core is to fix the plant roots in the planting basket and let the roots hang naturally into the plant nutrient solution. This nutrient solution can Instead of natural soil, it provides water, nutrients, oxygen, temperature and other growth factors to plants, so that plants can grow normally and complete their entire life cycle. [0003] There are three main types of hydroponic facilities: 1) Nutrient liquid film hydroponics (NFT). Plants are planted in a shallow, flowing nutrient solution, and the roots are suspended to increase their oxygen uptake. Use a long and narrow black polyethylene film, place the grown seedlings and seedling blocks in a row according to the pl...

Problems solved by technology

The cultivation objects of the above-mentioned hydroponic device are small plants with roots such as seeds and tender seedlings. The space of the hydroponic tank is small, and it is impossible to install forest branches. In addition, it is impossible to simulate the development mode of tree branches growing obliquely at a certain angle on living trees, and long-term immersion may easily cause bacterial growth and anoxic rot at the end cuts of forest branches. In addition, the above-mentioned hydroponic system also It needs to be used under greenhouse conditions, and has high requirements for related supporting equipment

[0006] The existing hydroponic method of cutting branches of forest trees is extensively operated. After the branches of the forest trees are cut off from the trees, they are moved into the greenhouse and directly inserted into buckets or porcelain vats, and the method of artificially injecting water into them is used for hydroponic cultivation. It must be operated in a greenhouse, and the old water in each bucket must be pumped out manually and then injected with new water to prevent the ends of the branches from rotting due to long-term soaking and lack of oxygen. Common pollutants cannot be removed in time

The branches stand vertically in the barrel, which is quite different from the growing environment of trees growing obliquely, which often leads to insufficient water supply at the top of the branches, and because the branches are upright, it is relatively difficult to collect and pollinate pollen, which is not conducive to later experiments Research and related processing

The operation workload is heavy, time-consuming, laborious, large investment, high cost, and the hydroponic environment of each branch is relatively independent, it is difficult to achieve the unity of hydroponic conditions, which is not conducive to the comparative analysis of experimental research
